Question #21379
Does the power needed to raise a box onto a platform depend on how fast it is raised?
Expert's answer
Power can be expressed asP = F*V
where F is force (F=mg in our case) and V is velocity
Hence, for bigger velocity there has to be bigger power.
Power is proportional to velocity
where F is force (F=mg in our case) and V is velocity
Hence, for bigger velocity there has to be bigger power.
Power is proportional to velocity
